Progress's oxidizer tank is 'suspect'?
Progress's oxidizer tank is 'suspect'?
Does anybody have any details? Will this change the undocking procedures? What did they know, and when did they know it? Aug 18 ISS Status Report: On 8/20-21, MCC-Moscow/TsUP is planning to refuel the FGB tanks from Progress 10P. The transfer of fuel (UDMH) will be preceded, as usual, by a vacuum purge of the fuel (ZUG) lines, to vent residuals in the plumbing between Progress and SM into space. The purge, scheduled for tomorrow (8/19) will be recorded on video. [As previous recordings have shown, there will be a stream of gas-liquid mixture resembling snow. The fuel will flow with variable intensity of the liquid phase stream, like "fireworks". Since the 10P's oxidizer tank is suspect, there will be no oxidizer transfer (nitrogen tetroxide, N2O4).] |

They found that they did not consume balanced levels of fuel and oxidizer and were not sure about what to do with the remaining part. Seems they want to transfer it to the FGB. Perhaps they can counterbalance the load on a future progress. The all singing all dancing Soviet technology comes through once again...

I wouldn't poke fun at the Russians when they currently have the only operational means to put men into space and resupply ISS. Ex-Soviet technology isn't necessarily the best or the worst, it's just different. It's not poking fun, it's a serious reminder to those in this group who doggedly insist that Soviet technology is magically better than that of the US, despite abundant evidence to the contrary.

Flaws in Russian hardware
"Jorge R. Frank" wrote in message ...
And specifically aimed at the folks who never miss a chance to point out flaws in NASA technology, but when Russian technology is also shown to have flaws, they are either silent, or (even more curious), they snip all references to the technology's origin from their reply. Hmmm ... perhaps a new thread called "flaws in Russian space hardware" is in order. |
